The purpose of this study was to evaluate the performance of enhanced CT in making a diagnosis of combined hepatocellular and cholangiocarcinomas (HCC-CCs) by comparing CT findings with histologic findings.
One third (nine of 27 cases) of the combined HCC-CCs were correctly diagnosed on enhanced CT by detailed analysis of the enhancing pattern around or within the mass. Various factors such as an atypical enhancing pattern, the size of each component, and the presence of a mass composed of intermediate tumor cells-that is, cells with intermediate characteristics between HCC and CC-were found to be the causes of misdiagnosis of combined HCC-CC on enhanced CT.
本研究的目的是通过将CT表现与组织学表现进行比较，评估增强CT在诊断肝细胞癌合并胆管癌（HCC-CC）中的性能。
通过对肿块周围或内部强化模式的详细分析，三分之一（27例中的9例）的HCC-CC在增强CT上得到正确诊断。发现诸如非典型强化模式、各成分大小以及由中间肿瘤细胞（即具有介于HCC和CC之间的中间特征的细胞）组成的肿块的存在等各种因素是增强CT上HCC-CC误诊的原因。
